NASA space telescope maps magnetic fields of ‘Lighthouse’ pulsar

by quasarn01 | Jul 10, 2026 | Astronomy

For the first time, scientists have used NASA’s IXPE (Imaging X-ray Polarimetry Explorer) to directly measure the magnetic fields of PSR J1101−6101, a pulsar located within what is often referred to as the Lighthouse Nebula. The results provide new insight into...

Could exoplanets locked in eternal day and endless night support life?

by quasarn01 | Jul 10, 2026 | Astronomy

Ever so slightly bigger than Earth, the exoplanet LHS 3844b orbits its parent star, LHS 3844, a red dwarf 48.5 light-years from our solar system. Its rotational speed mirrors its orbital speed. The result? One side of LHS 3844b is perpetually bathed in scorching...
